assuming the tube was full of water

No, you wouldn't have 80lbs of pressure, you'd have 80lbs of force.
This is why it's not a good idea to ask homework questions here unless you understand the method. Most of the answers as well as yourself are confusing force with pressure. Pressure is total force divided by the area the force is acting over. To work out the area the total force of the column of water is working over, you have to work out what area a foot's worth in height of a gallon of water covers to get the area of the end of the tube.
From this you can then easily calculate the pressure as you know the total force from the total amount of liquid.
Congratulate your teacher for me for confusing the Yahoo Answers lot!

Yes. A pint's a pound the world around and there are 8 pints in a gallon or 10 gallons and 80 pounds total weight for a ten foot column. A foot of water exerts a unit pressure of 0.433 pounds per square inch or 4.33 pounds per square inch for a ten foot column. Dividing 80 pounds by 4.33 pounds per square inch indicates that the cross-sectional area of the tube is about 18.48 square inches which can be used to calculat the approximate inside diameter of the tube (if round).

these other answers dont even make sense, 4 lbs? there isnt even a reference to the tube
it doesnt matter how much water is per foot, there will be the same amount of pressure at the bottom
whether its a tube, a pool, or the ocean
pressure will be measured as the unit weight of water multiplied by the head
62.4 lbs-ft * 10 ft = 624 lbs

If the liquid was water then the pressure at the very bottom would be in round numbers 4.33 psi.
A column of water will exert 0.433 psi per foot of height.
You asked for pressure. By convention, pressure is in force per square unit, i.e. pounds per square inch, pounds per square foot, etc.

A gallon of water is approximately 8.345404 pounds. If you have a gallon per foot, then at ten feet you would have 83.45404 pounds total. Therefore the bottom would be carrying at least 83.45404 pounds of water and the pressure is 83.45404 pounds.

A column of water at 65 degrees F will exert a pressure of 1 psi at 2.31 feet, so you should get approximately 4.33 psi at the bottom.

You may. This depends on where you hold it, and the width of the tube.But if your talking about the gallons i know, which are about 5 pounds filled with any liquid than no.Gravity has a major role in this project.So does the density of the liquid.

That depends on the radius of the tube and the density of the fluid.

No, approx 5lb per square inch of pressure
